HEEL-NAILING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 569,055, dated October 6, 1896.

Application filed September 24, 1889. Serial No. 324,919. (No model.)

To all whom, it may concern.-

Be it known that I, FEEEBORN F. RAY- noND, 2d, a citizen of the United States, residing at Newton, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in I-Ieel-Nailing Machines, of Awhich the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming 1o a part of this specification, in explaining its nature.

The invention relates especially to devices for holding and centering top lifts and heelblanks of boots and shoes.

Referring to the drawings, Figure l is a view in plan of a top-lift spanking-block provided with myinvention. Fig. 2 is a section upon the dotted line .fr 5c of Fig. l. Fig. 3 is a section upon the dotted line y fj of Fig. 1.

zo Fig. 4 is a section upon the dotted line e' ,e of

Fig. 2.

A represents a spanker-block. Upon it are mounted the front gages B B and a back gage B2. Each of the front gages is represented as comprising a slide-block 6 and a forward extension 6', having the angular edge 62 extending to the shoulder 63. Each slide may also have the side shoulder 64. These gages are preferably made in one piece and 3o have a dovetail section 65, arranged to enter a dovetail recess 66, extending from each side edge of the spanker-block. There is also formed through the spanker-block from end to end the hole 67, which connects orl opens into the dovet-ail recesses 66, and there extends from each of the gage-blocks into said hole a stud 68, (see Figs. 2 and 4,) and these studs are connected with each other by a closing-spring 69, contained in said cross-hole 4o 6T and acting to draw the gages toward each other or upon the top lift and to maintain them in such position. Each gage-block may also have the adjustable stop C for limiting and governing the extent of its closing or inward movement. The back gage B2 preferably has diverging arms 610, extending from a slideblock 611. The slide-block has a dovetail base 612, which enters a dovetail recess 613 in the rear part of the spanker-block, and there is formed in the spanker-block, extending from 5o the rear or back end, a hole 614, which opens into the dovetail recess 613', and'into which a stud 615 on the slide-block 612 extends, and this hole contains a spring 616, fastened at its front end 61T and secured at its rear end to' 55 the stud 615. The office of the spring is to draw the slide and diverging arms of the gage forward toward the front gages.

Instead of connecting the gages B B with each other by a common spring, there may be 6o used two springs,one for each gage-block,or if one spring is employed it may be fastened in its hole at the center of its length, which will in eifect answer the purpose of two springs.

In use the back edge of the top lift or heelblank is pressed against the surface 62 of the front gages and the gages thereby moved from each other sufficiently to allow the top lift or heel-blank to comek into contact with the back gage and pass the shoulders 63, and 7o after the shoulders 63 are passed the gages close upon the heel-blank, the shoulders coming in front of the breast, and the back gage pressing against the back of the heel forces it into contact with the shoulders, so that the 7 5 top lift or heel-blank is held centered between the arms 610, the shoulders 63, and between the shoulders 64. As above stated, however, it is not always essential to employ the shoulders 64. 8o

Having thus fully described my invention,

I claim and desire to secure by Letters Patent of the United Statesl. The combination in a top-lift or heelblank holding and centering deviceY of the 8 5 block Ahaving the recesses 66, the slideblocks 6 6', one in each recess, the gage-blocks B B attached respectively to said slide-blocks and a spring or springs for moving said slideblocks toward each other, as and for the pur-A 9o poses described.

2. The combination in a top-lift or heelblank holding and centering device of the block A, having the recesses 66, the gageblocks B B' arranged to` slide therein, the hole 95 614 connecting the recesses 66, studs upon the blocks to enter said recesses and a spring-` eonmovements in relation to each other, as and :meeting said studs contained in the hole Z114, for the purposes described. substantially as described. 1 IT 1 r T c,
